This is what that little script spits out when I ran it on an old motherboard with onboard video. This is on a minimal install of Ubuntu 16.04 LTS with ratpoison as the window manager, no display manager, and no xorg.conf.

If you look at
man Xorgthere is a -configure option that will create an xorg.conf file for you.
caveat: I have never done this, and I don't know how it works.
NUC:~$ Xorg -configure (EE) Fatal server error: (EE) Server is already active for display 0 If this server is no longer running, remove /tmp/.X0-lock and start again. (EE) (EE) Please consult the The X.Org Foundation support at http://wiki.x.org for help. (EE)
Xorg :0 -configurewhich ran and the last line in the log said
No devices to configure. Configuration failed.I searched around, and so far have not found anyone who got an xorg.conf successfully created with -configure.
If you actually get it to work, let us know how you did it.
You can force the EDID with a kernel command line in your grub configuration.

Scroll down to;

Does your audio have any options relating to the HDMI and/or EDID? I have had similar issues with HDMI/DVI and having a KVM in the mix. Can be solved on the KVM config side.
Is your NUC the one with TOSLINK? Does your Yammy have an optical port?
Lots of ways to skin the feline.
I have not needed to edit an Xorg.conf in many years.
YMMV
:)
So far I'm getting similar results.
NVidia has a really cool program for generating an xorg.conf file for you, but unfortunately this isn't an NVidia Vid.
At this point, I'm pretty sure my solution is going to be to generate a good and tight xorg.conf file, but I'm going to have to do some more research on that. Again, my biggest problem is the way the problem presents. I only get the 'rain' on screen after the thing has sat overnight, or a similar long period of time has passed. Fortunately, I really don't use the console on this box very much. It's pretty much an over-engineered music player for the most part, though I do have a bunch of vids on it for when I run out of books to read. (which doesn't happen often).
